Lightact v3.1.1

Today we are releasing Lightact v3.1.1! It is packed with new pixel mapping and computer vision features. And to give you even more tools, we are upgrading our Unreal Engine plugin, so you have even more options when using Lightact with Unreal Engine.

DMX mapping

Fixture placement rendering has been re-built from the ground up and its efficiency increased by an order of magnitude. Now you can easily render tens of thousands of pixels with no significant FPS drop.

Fixture placement with OBJ files

We’ve upgraded eDMX (Art-Net) fixture import with OBJ files! Now you can import an obj file and filter the objects within by several attributes and place different fixtures based on those filters. This allows you to use one obj file to place different types of fixtures and to exclude certain objects from the placement (props, for example).

On top of that, Lightact can also grab rotations of the objects in the obj file and orient your fixtures accordingly. This enables a truly smooth workflow from your 3D modeling application to Lightact.

Fixture placement with CSV files

Based on a user-request (thanks, Robb!) we’ve also added a Fixture placement with CSV file! This allows you to create a simple CSV file containing locations, rotations, fixture type and DMX address of all the fixtures and create a fixture placement based on this file.

Computer vision

We’ve added a number of new computer vision nodes. Besides Optical flow that’s been here since a few months ago, now you also have MOG2 background subtraction, Find contours and Find circles node. You can also pass data from Find contours and Find circles node to Unreal Engine for advanced real-time VFX.
